Features

Sharded Pub/Sub

Sharded Pub/Sub was introduced in Redis 7.0 in order to help scaling the usage of Pub/Sub in cluster mode.

Reference: https://redis.io/docs/manual/pubsub/#sharded-pubsub

A dedicated adapter can be created with the createShardedAdapter() method:

import { Server } from 'socket.io';
import { createClient } from 'redis';
import { createShardedAdapter } from '@​socket.io/redis-adapter';

const pubClient = createClient({ host: 'localhost', port: 6379 });
const subClient = pubClient.duplicate();

await Promise.all([
  pubClient.connect(),
  subClient.connect()
]);

const io = new Server({
  adapter: createShardedAdapter(pubClient, subClient)
});

io.listen(3000);

Minimum requirements:

• Redis 7.0
• redis@4.6.0

Added in e70b1bd.

Support for node-redis cluster

The redis package now supports Redis cluster.

Added in 77ef42c.

Subscription modes

The subscriptionMode option allows to configure how many Redis Pub/Sub channels are used:

• "static": 2 channels per namespace

Useful when used with dynamic namespaces.

• "dynamic": (2 + 1 per public room) channels per namespace

The default value, useful when some rooms have a low number of clients (so only a few Socket.IO servers are notified).

const io = new Server({
  adapter: createShardedAdapter(pubClient, subClient, {
    subscriptionMode: "static"
  })
});

Added in d3388bf.

Huge thanks to @​winchell for helping!

v8.1.0

Compare Source

The socket.io-adapter package was added to the list of peerDependencies, in order to fix sync issues with the version imported by the socket.io package (see f07ff7b).

Features

Automatic removal of empty child namespaces

The close() method was implemented, in order to be used with the new cleanupEmptyChildNamespaces option.

Reference: https://github.com/socketio/socket.io/releases/tag/4.6.0

Added in fe89f7e.

v8.0.1

Compare Source

This release pins the socket.io-adapter package to version ~2.4.0 instead of ^2.4.0.

v8.0.0

Compare Source

Dependencies

• bump notepack.io to version ~3.0.1 (#​464) (c96b2e7)

Features

• add option to allow usage of custom parser (#​471) (73f6320)

Example with msgpackr:

import { unpack, pack } from "msgpackr";

io.adapter(createAdapter(pubClient, subClient, {
  parser: {
    encode(val) {
      return pack(val);
    },
    decode(val) {
      return unpack(val);
    }
  }
}));

• remove deprecated methods (fb760d9)

BREAKING CHANGES

• the remoteJoin(), remoteLeave(), remoteDisconnect()
  and sockets() methods are removed in favor of the official alternatives

Related: socketio/socket.io@b25495c

• the format of Date objects is modified in a non
  backward-compatible way, as notepack.io now implements the MessagePack
  Timestamp extension type.

Reference: https://github.com/msgpack/msgpack/blob/master/spec.md#timestamp-extension-type

Previous versions of the adapter will not be able to parse the Date
objects sent by newer versions.
